Answer:
[tex]-1.4[/tex]
Step-by-step explanation:
The slope of a line is the change in the line. It can be found using the formula;
[tex]\frac{rise}{run}[/tex] or [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
Substitute in the given points, and solve for the slope;
[tex]\frac{y_2-y_1}{x_2-x_1}\\\\= \frac{2-9}{11-6}\\\\= \frac{-7}{5}\\\\= -1.4[/tex]
